Mechanical Zinc Coating Procedure under Conditions of Vibration Mechanical-Chemical Impact

Abstract

The purpose of the investigation carried out is the study of regularities in structural-phase changes and mechanical-chemical processes occurred in a surface layer under the influence of outer and inner technological factors. As experimental equipment there was used a vibration horizontal plant of UVG4x10 type. Working environment consisted of porcelain balls of 4mm diameter, PU-20 zinc powder and an aqueous solution of zinc chloride, and as abrasives – steel plates of 10x10 mm. As a result of the investigations there was determined a mechanism of coating formation, technological regulations for its application were established, surface morphology was investigated. The coating obtained exceeds the electrolytic one by a factor of 1.5 on corrosion resistance due to the absence of a hydrogenated layer.
